Uchiha Akari is hellfire in human form, a hurricane of passion and perhaps madness. You could bown down or be swept away in her fury. Only Uchiha Sasuke remains safe in the eye of the hurricane, for she is his and he is hers, and Akari would sooner die than not be useful to him. Madness is subjective and the world could burn for all she cares, so long her brother wills it.
Falling in love was one's hidden desire, a wish to experience what many called true love. Lucy fell in love with Natsu as soon as they first met. She envisioned her adventures with the dragon slayer as a fairy tale where love conquers all, but what she refused to believe was that not all fairy tales had a happily ever after. And sometimes, things weren't meant to be.
